Plz help I need to pass this assignment!
1. Which mechanism of transport takes place when substances move from a region of low concentration to a region of high concentration?
A. Active
B. Diffusion
C. Hypotonic
D. Passive

2. Which type of molecule provides cells with energy?
A. Carbohydrate
B. Nucleic Acid
C. Protein
D. Water

5. Plant cells and animal cells were observed under a microscope. The characteristics of two cells are listed below.

Cell P: Does not capture sunlight
Cell Q: Has cytoplasm but no chloroplast

Which statement about the two cells is correct?
A. Cell Q has a cell wall
B. Cell Q also has a large vacuole
C. Cell P also has a large vacuole
D. Cell P also has a cell membrane

Answer:

1. A
2. A
5. D
Reason:
1. Active transport is the movement of molecules from a region of low concentration to a region of high concentration with expenditure of energy.
2. Carbohydrate is the main source of energy to body because it is broken down during repsiration to produce ATP.
5. P cell does notcapture sunlight so it has no chloroplast.it mean it is not a plant cell having no cell wall and no large vacoule. it will be animal cell having cell membrane.
