There are diverse plant species all over the world, and they vary in each habitat.
There are diverse plant species all over the world, and they vary in each habitat.
The statement is true because plant species are diverse and live in many different habitats around the world. Plants adapt to their environment and are perfectly suited to living in that location. Some habitats feature many species of plants, while others only host a few.

What can you conclude about plant diversity in the parking lot compared to the park with a lake?
What can you conclude about plant diversity in the parking lot compared to the park with a lake?
When comparing the park with a lake to the parking lot, the observations in the data table show readers that there is less plant diversity in the parking lot. The parking lot is human-made, and there are lots of buildings and cement rather than grass and trees like a natural habitat would have.

Which habitat has greater plant diversity? Which piece of the text supports the claim?
- Amazon Rainforest: In the Amazon Rainforest is rains almost every day. There are very tall trees that create a canopy, and the ground of the forest is covered in plants. The plants on the ground try to grow wide or tall to reach sunlight. The very tall trees can block much of the sunlight.
- The Sahara Desert: The Sahara Desert is made entirely of sand. It rarely rains and is very dry. There are only a few plants, and they have small leaves. The sand is scorching and moves every time it is touched; when the wind blows, the sand shifts in all directions.

Plant species are diverse and live in many different habitats around the world. Plants adapt to their environment and are ideally suited to living in that location. Some habitats feature many species of plants, while others only host a few. In the two habitats listed the Amazon Rainforest has a great diversity of plants when compared to the Sahara Desert. The text evidence that supports this claim "...the ground of the forest is covered in plants." illudes to many plants being present in the rainforest.

What would the Sahara Desert have only a few plant species?
The Sahara Desert only has 500 plant species, which may seem like a large amount, but the Amazon Rainforest has nearly 80,000! The reason that the desert has so many fewer plant species and is less diverse is that the ground is scorching, shifts in the wind, is made of sand, and the region receives little to no rain. These conditions make it very difficult for plants to survive unless they are well adapted.

Why would the Amazon Rainforest be such a diverse plant habitat?
The Amazon Rainforest is a very diverse plant habitat because it has all of the things a plant could need to grow and survive. The rainforest is a wet, humid, and warm place that offers plenty of water and sunlight. Many animal species rely on these plants to make homes and for food. Plants have adapted to this environment and thrive in the conditions.

Grasslands - The grasslands in the Northern hemisphere are vast, open terrains with flowers and grass. There is enough rain to support small amounts of trees and lots of grass. The soil is thin and dry, and there are often wildfires. The temperatures range from very cold (in the negatives) to comfortable (in the mid-70's).
Why are the grasslands not a more plant diverse habitat?

Why are the grasslands not a more plant diverse habitat?
Grasslands are home to many plants and animals, but they are not as plant diverse as one may think. All of the answer choices list reasons why the grasslands don't have an abundance of varying plant species. The soil is thin and dry, and not all plants are adapted to this type of earth. There are frequently wildfires, and many plant species cannot recover after these incidents. Finally, there is little rainfall, so many trees and plants cannot function in this habitat. The plants that live in grasslands and do well have evolved and adapted over many years to live in this type of habitat.

What do plants need to grow?
What do plants need to grow?
For plants to grow and survive, they need sunlight and water. Water is collected through the roots of the plant and absorbed from the soil. Sunlight is collected through the leaves of the plant to use in the process of photosynthesis to make food. Plants cannot live without sunlight and water.

Justin wants to plan an investigation to see if a plant can live without sunlight or water. What list of materials is appropriate for this type of investigation?
If Justin wants to plan an investigation, an important part is to have the right supplies or materials. Justin will need two plants, one to place in the sunlight and one in the dark, water for the plant in the sunshine, a ruler to measure growth, and paper and pencil to record observations. The other lists are incomplete or have materials that are not needed for this investigation.

Brandon is curious about what keeps plants alive and helps them to grow. Which answer choice is a testable, scientific question that relates to the topic?
Brandon is curious about what keeps plants alive and helps them to grow. Which answer choice is a testable, scientific question that relates to the topic?
Most investigations or experiments start with a question. In this case, Brandon is wondering about keeping plants alive and helping them grow. A scientific question must be testable, meaning someone can collect data and observations, and it should be related to what the person was wondering. The correct answer choice is testable and related. Water and sunlight are essential to a plant's survival, so they would be good variables to test.

Virginia is planning an investigation to test what would happen if she does not give rose plants sunlight or water. Her teacher tells her to state her hypothesis or prediction of what she thinks the results will be. Which hypothesis is most reasonable?
Virginia is planning an investigation to test what would happen if she does not give rose plants sunlight or water. Her teacher tells her to state her hypothesis or prediction of what she thinks the results will be. Which hypothesis is most reasonable?
A hypothesis is stated before an investigation or experiment is performed, and the evidence collected will either support or will not support the prediction. A hypothesis should be reasonable and related to the topic. Virginia is testing what would happen to plants without water or sunlight; these are two critical pieces to a plant's survival. Using background knowledge or personal experiment, a prediction can be made that the plants will not survive. "I believe the rose plants will not survive without sunlight or water. They will wilt and die over time." is the most reasonable hypothesis.

Jennifer wants to test whether plants can survive without sunlight and water. Which answer choice represents the BEST plan to investigate this?
Jennifer is testing whether plants can survive without sunlight and water, so those are the only two variables that will change. Everything else in the investigation should remain the same. The same pots, same dirt, same amount of water each day, same type of seeds, and the same amount of sunlight or darkness should be maintained throughout the investigation. "Get four identical pots and fill each with the same amount of dirt—plant three sunflower seeds in each container—place two in a window and the other two in a dark closet. Water one of the plants in the window daily, water one of the plants in the dark closet daily—record plant growth and observations." is the most controlled and complete investigational plan.

Nick is planning an investigation to see if plants grow better in the dark or somewhere sunny. Which data table set-up would be best for him to use during this investigation?
In this investigation, Nick is only testing if plants grow better somewhere dark or sunny. The water the plants receive should be the same, and there should be some plants in the sun and some in the dark so they can be measured and observed. There have to be plants in both locations to compare growth.

Andrew wants to investigate if plants need water to survive. Which data table set-up is most appropriate for this investigation?
Andrew wants to investigate if plants need water to survive. Which data table set-up is most appropriate for this investigation?
The only test variable in this investigation is whether the plant gets water or not. Andrew is testing if water is needed for plants to survive. All of the test plants should be in the same location, and some should get water while others do not so they can be compared to one another. If all the plants get water, then Andrew will not know what would happen without water. If he has some plants in different locations, he won't know if it is the water or the area that stopped a plant from surviving.

What does it mean to investigate?
What does it mean to investigate?
To investigate something or to participate in an investigation means to discover, study, or research. When scientists have a question, they will come up with a plan to try and answer it. If someone wanted to investigate a plant's growth, they could test the type of soil, amount of water or sunlight, or the type of plant. They would collect data and make observations about the plants; this would be an investigation.
