Are plant cells eukaryotic or prokaryotic? (1)
Eukaryotic (DNA enclosed in the nucleus)
What is the most destinctive structure in plabt cells (2)
The cell wall outside cell membrane, forms an outer lining
What is the cell wall made up of (1)
Cellulose
True or False: (1)
All cells have a cell wall
False, only plant cells
What is the FUNCTION of a cell wall (1)
Provide support and rigidity
Name the 3 cell wall layers (3)
- cell wall
- secondary cell wall
- middle lamella
What is the function of the outside cell membrane (3)
- rigidity
- strength
- protection against mechanical stress and infection
WHAT IS the cell membrane (3)
- the outer boundary of the cell
- encloses the cytoplasm and organelles of the cell
- the plant cell is inside the membrane
What is the FUNCTION of the cell membrane (2)
It’s semi-premeable, it allows certain things that are needed in and blocks others out
What do chloroplasts look like (3)
- an elongated/disc shaped organelle containing chlorophyll
- it’s 2 membrane and its structure looks like a stack of coins
- flattened structures
What is the FUNCTION of chloroplasts (1)
- they allow photosynthesis
What is chlorophyll (2)
- a green pigment that obsorbs sunlight energy to make food
- it turns light energybinto chemical energy
What are the FUNCTIONS of the vacuole (4)
- known as cell storage center (main function)
- secretion
- excretion
- storage
WHAT IS a vacuole (2)
- in plant cells there is a large membrane bound chamber = vacuole
- in the cytoplasm of most cells
What is the tonoplast (1)
A vacuole surrounded by a membrane
WHAT IS the Golgi complex (3)
- golgi bodies look like tge endoplasmic reticulum
- it’s near the nucleus
- almost in all eukaryotic cells
what is the FUNCTION of golgi complex (2)
- the package center
- to procces and package macromolecules synthesized from other parts of the cell
WHAT IS a ribosome (3)
- the smallest and most abundant cell organelle
- made up of RNA and protein
- found in all cells as protein is needed for survival
What is the FUNCTION of ribosomes (1)
- sites for protein synthesis
- protein factories
WHAT IS the edomplasmic Reticulum (ER) [3]
- a membrane compartment
- flattened sacs side by side
- a large network interconnecting membrane tunnels
What are the 2 types of ER (2)
- Rough ER with ribosomes on the outside
- Smooth ER
What are the 2 different FUNCTIONS of the ER (2)
- rough: protein manufacturerer and transport in cell
- smooth: site of hormone + lipid (fat) manufacture
WHAT IS the mitochondria
- surrounded by 2 membranes
What is the FUNCTION of the mitochondria (4)
- power plants
- converts glucose into enrgy molecules (ATP)
- process their own DNA
- helps with duplication and multiplication
