Plant cell?
.Cytoplasm
.Nucleus
.Cell membrane
.Cell wall
.Mitochondria
.Vacuole
.Chloroplast
Nucleus
Contains the DNA and controls the cell
Cell membrane
Controls what goes in and out of the cell
Cytoplasm
All chemical reactions occur here
Mitochondria
Respiration occurs inside to release energy for the cell to use
Cell wall
Protects the cell and gives it structure
Chloroplasts
Carry out photosynthesis to make food for the plant
Vacuole
Filled with cell sap and gives cell shape
Egg cell: Job
Reproduction.
Egg cell: features
Nucleus contains 1/2 genetic info.
Energy = enough to allow egg to develop if it’s fertilised.
Sperm cell: job
Reproduction
Sperm cell: Features
contains 1/2 genetic info.
Has tail to swim and meet the egg
Nerve cell: job
Help nerve impulses move round the body
Nerve cell: features
Long & thin
Send electrical impulses large distances around the body
Plant palisade cell: job
Help the plant photosynthesis and make food
Plant palisade cell: features
Lots of chloroplasts to trap light energy for photosynthesis
Plant root cell: job
Help plant get water through the roots
Plant root cell: features
Large surface area to absolve more water from soil
Diffusion
Movement of particles from a high concentration to a low one
Substances that move in & out of cells by diffusion
.oxygen - respiration
Glucose- respiration
Carbon dioxide- out: respiration in: photosynthesis
Water: root hair cells
What are unicellular organisms made from
Only one cell
What are multicellular made up of
More that one cell
What is the respiratory system
Gas exchange in and out of the body
Reproductive system
Produce young
Nervous system
Sense and react to our surroundings
Circulatory system
Transports blood round the body
Organ system
A group of organs with related functions, work together to perform body functions
Digestive system
Let’s you eat and excrete food and drink
What are organs
Group of tissues working together to perform functions
Tissues
Group of cells, similar structure, work together to perform a shared function
