17
Q

Nucleolus

A

Dark dot inside nucleus, makes ribosomes

18
Q

Nuclear envelope

A

Nuclear membrane

19
Q

Call membrane/plasm membrane

A

Made of lipid and protein, controls what enters and leaves the cells. All cells have a cell membrane

20
Q

Cell wall

A

Only animal cell don’t have a cell wall, make up of cellulose

21
Q

End plasmid reticulum

A

Export system

22
Q

2 kinds of endoplasmic reticulum

A

Smooth, rough

23
Q

Smooth endoplasmic reticulum

A

Does not have ribosomes, helps detox

24
Q

Rough endoplasmic reticulum

A

Has ribosomes

25
Q

Ribosomes

A

Made in nucleolus

26
Q

Function of ribosome

A

Makes proteins

27
Q

Ribosome location

A

Floating in cytoplasm, and attached to the endoplasmic reticulum

28
Q

Golgi bodies

A

Modifying and packaging materials in a cell

29
Q

Mitochondria

A

Sure of cellular respiration (breaking glucose into energy into ATP)

30
Q

Cristae

A

Fold of a mitochondria, folds for more surface area

31
Q

Plastids

A

In plant cells, contains pigment in a organelle. Photosynthesis

32
Q

3 types of plastids

A

Leucoplast, chromoplast, chloroplast

33
Q

Leucoplast

A

Stores starch, stores colorless things

34
Q

Chromoplast

A

Contains other colors/pigments

35
Q

Chloroplast

A

most common, contains chlorophyll

36
Q

Vacuoles

A

Stores water

37
Q

Plant cells vacuoles

A

The only cell that had large central vacuoles

38
Q

Lysosomes

A

Breaks down waste in cells

Ex: white blood cells

39
Q

Centrioles

A

Plant cells don’t have this, helps in mitosis, breaks off of cytoplasm, it’s in animals cells

40
Q

Structures for movement

A

Locomotion,

2 types- cilia, flagella

41
Q

Cilia

A

Little hairs

42
Q

Flagella

A

Whip lick
