Q

what are the 3 components of the cell theory

A

all cells arise from pre existing cells, a cell is the basic structural and functional unit of living organisms, all living organisms are composed of one or more cells.

this organelle consists of two types of fibers called microfilaments and microtubules

A

cytoskeleton

17
Q

this part contains the instructions for making proteins and other important molecules

A

nucleus

18
Q

this is the semi-fluid portion found inside the nucleus

A

Nucleoplasm

18
Q

this organelle puts the “ finishing touches “ on proteins before they are shipped off to their final destinations

A

Golgi apparatus

19
Q

this large structure in a plant cell is filled with water creating turgor pressure

A

Vacuole

20
Q

this is the site of photosynthesis in a plant cell

these may be found free floating in the cytoplasm or attached to the endoplasmic reticulum

A

ribosomes

22
Q

this part of the cell contains internal folds of membrane called cristae

A

mitochondria

23
Q

this part of the cell is involved with cell movement, cell shape, and the separation of chromosomes during cell division

A

cytoskeleton

24
Q

this organelle has the unique ability to absorb the energy from the sun and convert it into a molecule of glucose

A

chloroplast

25
Q

the type of endoplasmic reticulum to which no ribosomes are attached
