2 Cells Flashcards
1
Q
Structures of a plant cell
A
- cellulose cell wall
- cell membrane
- cytoplasm
- nucleus
- large vacuoles containing cell sap
- chloroplasts containing chlorophyll
- starch grains
- regular shape
2
Q
Structures of an animal cell
A
- no cell wall
- cell membrane
- cytoplasm
- nucleus
- small vacuoles
- glycogen granules
- irregular shape
3
Q
Structures of a bacteria cell (4CPR)
A
- cell wall
- cell membrane
- cytoplasm
- circular DNA
- plasmids
- ribosomes
4
Q
Function of cellulose cell wall
A
- full permeable
- cellulose has fibers that crisscross to form a strong covering for the plant cell, protecting and supporting the cell
5
Q
Function of cell membrane
A
- thin layer of fat and protein
- partially permeable
- controls substances moving in and out of the cell
6
Q
Function of cytoplasm
A
- jelly-like substance
- contains many dissolved substances, especially proteins
- site of many different metabolic reactions
7
Q
Function of nucleus
A
- stores genetic information on chromosomes made of DNA
- helps the cell make the right sorts of protein
8
Q
Function of vacuoles
A
- plant cells have large vacuoles to maintain its regular shape
- animal cells have small vacuoles called vesicles which may contain food or water
9
Q
Function of chloroplasts
A
contains chlorophyll which absorbs energy from sunlight to make food for the plant via photosynthesis
10
Q
Function of mitochondria
A
carries out aerobic respiration by using oxygen to release energy from glucose
11
Q
Function of ribosomes
A
site of protein production where amino acids are joined together in a long chain
12
Q
How do you calculate magnification?
A
Image size over actual size
13
Q
How are new cells produced?
A
- by mitosis/division of existing cells
14
Q
Ciliated cell
A
- lining the trachea and bronchi
- moves mucus upwards
15
Q
Root hair cells
A
- found near the end of plant roots
- absorbs water and mineral salts
