Q

What is the major difference between protostomes and deuterostomes?

A

In protostomes the mouth is formed first and then the anus second. In deuterostomes, it is the other way around where the anus is formed first and then the mouth is formed second.

Q

small, dot like organelles that are either in the cytoplasm or attached to ER

A

Ribosomes

23
Q

What part of the cell makes proteins?

A

Ribosomes

24
Q

Most abundant organelle, found in all cells

A

Ribosomes

25
Q

Part of the cell where ATP/energy is made and released; bean shaped organelle.

A

Mitochondria

26
Q

transport system of the cell - for movement of materials around the cell.

A

Endoplasmic reticulum

27
Q

Part of the cell that makes lipids and hormones. it also modifies proteins.

A

Smooth ER

28
Q

This part of the cell produces proteins for export out oof the cell

A

Rough ER

29
Q

gel-like fluid (liquid) inside the cell.

A

Cytoplasm

30
Q

How does the Golgi apparatus work with the ER?

A

When a protein is made in the ER, something is made called a transition vesicle. It floats through the cytoplasm to the Golgi apparatus and is absorbed. From there, the vesicle moves to the cell membrane and the molecules are released out of the cell.

31
Q

storage sacs that store water and other liquids in the cell

A

vacuole

32
Q

Part of the cell that contains digestive enzymes that break down food, substances that are not needed, damaged cell parts, and viruses

A

lysosomes

33
Q

Large water sack in plant cells that helps the cell hold its shape

A

large vacuole

34
Q

Green sacs that contain chlorophyll

A

chloroplasts

35
Q

What organelle is responsible for helping with the process of photosynthesis?

A

chloroplasts

36
Q

Part of the cell outside of the cell membrane that gives strength and support

A

cell wall

37
Q

Where are ribosomes made in the cell?

A

nucleolus, a part inside the nucleus

38
Q

What is responsible for the “beads on a string” appearance of chromatin?

A

histones

39
Q

This structure is composed of DNA and proteins, mostly basic proteins called histones

A

chromatin

40
Q

This is the loose structure of chromosomes

A

chromatin

41
Q

This is what the chromosomes are called when the cell is not dividing.

A
