T1-Cells and movement Flashcards
name the 8 characteristics of life
M - movement R - respiration S - sensitivity H - homeostasis G - growth R - reproduction E - excretion N - nutrition
define the 8 characteristics of life
M - when a living organism moves a part of itself to change from its original position
R - a process in living organisms involving the production of energy ( intake of oxygen and release of carbon dioxide)
S - being able to react or sense stimuli in the environment
H - keeping a constant internal environment
G - the increase in number and spread of small or microscopic organisms
R - the action or process of making a copy of something. including the production of offspring by a sexual or asexual process.
E - when metabolic waste is eliminated from the body
N - to have the need to consume nutrients to survive
give an example of movement in an animal and plant
plant - a sunflower turning to face the sun.
animal - a dog walking.
give an example of respiration in an animal and plant
plant - photosynthesis.
animal - amoeba.
give an example of sensitivity in an animal and plant
plant - a venus fly trap sensing a bug.
animal - sense organs to tell them what is going on outside their bodies.
give an example of homeostasis in an animal and plant
plant - a cactus reflects sunlight to keep a constant body temp stable.
animal - bears keep a helpful body temp during hibernation.
give an example of growth in an animal and plant
plant - a tree growing in the woods.
animal - a cat getting bigger.
give an example of reproduction in an animal and plant
plant - cuttings (asexual reproduction).
animal - birds lay eggs to hatch new chicks.
give an example of excretion in an animal and plant
plant - plants do not excrete like an animal, they excrete through stomata in the leaves.
animal - an elephant excretes their body waste in the form of feces.
give an example of nutrition in an animal and plant
plant - suck up all nutrients in the soil like mineral oils.
animal - lions hunt animals like antelope to feed on as a source of food to survive.
what is an organelle?
small structure within a cell that carries out a specific function.
name all the cell structures found in an animal and the definition
nucleus - controls the cell as well as holds the DNA
cell membrane - a gate/barrier to keep unwanted substances out (waste) and wanted substances in (nutrients)
cytoplasm - jelly-like substance where chemical reactions occur
mitochondria - the powerhouse of the cell where
respiration takes place
ribosomes - where the protein is made
vacuole - a space in the cell with no cytoplasm, lined will a membrane and filled with sap.
name all the cell structures found in a plant and the definition
nucleus - controls the cell as well as holds the DNA
cell membrane - a gate/barrier to keep unwanted substances out (waste) and wanted substances in (nutrients)
cell wall - structural layer that gives the cell support
cytoplasm - jelly-like substance where chemical reactions occur
mitochondria - the powerhouse of the cell where
respiration takes place
ribosomes - where the protein is made
vacuole - a space in the cell with no cytoplasm, lined will a membrane and filled with sap.
chloroplast - contains chlorophyll and is where photosynthesis occurs
What is a cell?
cells provide structure for the body, take in nutrients from food and carry out important functions.
What is a specialised cell?
just cells designed to do a specific job
