Question

matching
match the description in column a with a term in column b. write the letter of the response in the blank
a

1. manufactures ribosome parts.
2. structure that forms the outer boundary of a cell.
3. encloses the cells genetic material.
4. not found in animal cells.
5. specialized structures performing specific functions.

b
a cell membrane
b organelles
c nuclear membrane
d nucleolus
e mitochondria
f nucleus
g cell wall
h ribosome

fill in the blanks

1. complete the following table by filling in the correct cell part or function.

cell part function
cytoplasm gel - like material inside cells.
nucleus directs cell activities.
endoplasmic reticulum folds proteins into complex shapes or other carbohydrates
manufactures substances important for cell functions.
mitochondria releases energy in the cell.
chromatin
chloroplast
vacuole stores water, food, and waste products.
golgi body
lysosome digests wastes.

longer answer

1. list three premises of the cell theory.
2. all living things are made up of one or more cells and the
3. the cell is the simplest unit that can carry out all
4. all cells come from other cells; they do not come from
5. which organelles does a plant cell have that an animal cell lacks?

Explanation:

1. Nucleolus makes ribosome parts. 2. Cell - membrane is outer boundary. 3. Nucleus encloses genetic material. 4. Cell - wall is not in animal cells. 5. Organelles have specific functions. For fill - in - blanks, match cell parts with known functions. For longer answers, recall cell theory and plant/animal cell differences.

Answer:

1. d
2. a
3. f
4. g
5. b

6.

• Endoplasmic reticulum: Folds proteins into complex shapes or adds other materials
• Chromatin: Contains genetic information
• Chloroplast: Site of photosynthesis
• Golgi body: Modifies, sorts, and packages proteins

1. All living things are made of cells. The cell is the basic unit of life. All cells come from pre - existing cells.
2. Cell wall, chloroplasts, large central vacuole.
