What 7 things do animal and plant cells have in common? |
- gogli apparatus - nucleus - endoplasmic reticulum - mitochondria - cytoplasm - ribosomes - cell membrane - lysosomes |
|
|
What are the 6 properties of animal cells?
|
1. Does not have a fixed shape 2. Does not have a cell wall 3. Does not have chloroplast 4. Does not have or has small vacuoles 5. Cell storage is glycogen 6. Has centrioles |
|
|
What are the 6 properties of plant cells? |
1. Fixed shape 2. Has cell wall 3. Has chloroplasts 4. Has a central vacuole 5. Does not have centrioles 6. Cell storage is starch |
|
|
What is are lamellas in plant cells? |
The lamella is in the middle of the cell wall and it cements the walls together for strength |
|
|
What does the cell wall consist of? |
It consists of pits which plasmodesmata extend |
|
|
What are plasmodesmata and what do they do? |
They are thin cytoplasmic threads that reach through the pits of the cell wall. They connect the cytoplasm of other cells and allow movement of substances between cells |
|
|
Give the function of the centriole |
1. It helps with the process of mitosis by forming spindle fibers that separate chromosomes 2. Helps with the motility of sperm cells and others |
|
|
Where is the cell wall found and by what is it formed? |
It is found in only plant cells; directly outside the membrane. The wall is formed by the membrane |
|
|
What does the cell wall consist of? |
It consists of cellulose fibers impregnated (soaked) with carbohydrates |
|
|
What does the primary cell walls consist of and describe the wall arrangement? |
The primary cell walls consists of fibers called pectin (sugary substance) arranged in a disorderly manner |
|
|
What does the secondary cell walls consist of and describe the wall arrangement? |
The secondary cell walls are arranged neatly by fibers called lignin and sometimes suberin (woody substance) |
|
|
Describe the function of the cell wall (2 points) |
1. Support and is responsible for the shape 2. Protection against mechanical injury |
|
|
Define the purpose of pits |
They allow transport between cells |
|
|
Where is the secondary cell wall located? |
Between the cell membrane and primary cell wall |
