What is the function of the chloroplasts?

Answer:

Chloroplasts capture energy from the Sun and convert it into chemical energy (food) for the plant through the process of photosynthesis. They also contain chlorophyll, which gives the plant its green color.

Check your understanding. What did you include?

A
capture energy from the Sun
B
convert energy from the Sun into chemical energy for the plant
C
give the plant the green color

In the text area below compare and contrast a cell membrane and cell wall.

Answer:

The cell membrane and cell wall both serve as protective barriers for the cell. All cells possess a cell membrane, which is a selectively permeable phospholipid bilayer that regulates the passage of substances into and out of the cell. In contrast, only certain cells, such as plant cells, have a cell wall. The cell wall is a rigid outer layer made of cellulose that provides structural support and maintains the cell's shape, which is especially important for plants to stand upright.

35

Check your understanding. What did you include in your answer?

A
A cell membrane, seen in plant and animal cells, is selectively permeable and made of a phospholipid bilayer.
B
The cell membrane and cell wall control what enters and leaves the cell.
C
The cell wall is seen in a plant cell, gives shape to the cell, and stores carbohydrates.
D
The cell wall is selectively permeable and made of cellulose, which causes plants to have a rigid structure.
