Question

cell parts and their jobs
in your textbook, read about cell parts and their jobs in section 2:2.

1. label the parts of these two cells in the spaces provided.

cell a
cell b

1. read the descriptions of cell parts below and write in the name of the cell part. use the color indicated to shade the pictures above.

a. use red for the part that gives the cell shape and holds the cytoplasm.
b. use green for parts that make food.
c. use brown for the thick outer covering that protects and supports the cell.
d. use blue for the part that stores substances.
e. use black for parts that get energy from food.
f. use purple for parts that carry hereditary information.
g. use pink for the cell part that helps with cell reproduction.
h. use orange for the parts that package and store chemicals.

1. list two cell parts found only in a plant cell.
2. where in a cell do most chemical reactions take place?

Explanation:

• a. The cell - membrane gives the cell shape and holds the cytoplasm.
• b. Chloroplasts make food through photosynthesis.
• c. The cell - wall is the thick outer covering in plant cells that protects and supports the cell.
• d. Vacuoles store substances.
• e. Mitochondria get energy from food through cellular respiration.
• f. Chromosomes (found in the nucleus) carry hereditary information.
• g. Centrioles help with cell reproduction in animal cells.
• h. Golgi bodies package and store chemicals.
• For plant - specific cell parts, cell - wall and chloroplasts are unique to plant cells.
• Most chemical reactions take place in the cytoplasm.

Answer:

1. (Requires labeling of cell parts in the diagram which cannot be done in text - based response but includes parts like nucleus, mitochondria, endoplasmic reticulum, etc. depending on the diagram)

2.
a. Cell - membrane
b. Chloroplasts
c. Cell - wall
d. Vacuole
e. Mitochondria
f. Chromosomes (in nucleus)
g. Centriole
h. Golgi body

1. Cell - wall, Chloroplast
2. Cytoplasm
