Flashcards in Yr9 Life Processes - General Deck (36):
An object that carries out all the life functions
An object which had never been alive
The building blocks of life
Moving the whole or part of the organisms
Creating useful energy from food.
Able to detect and respond to environmental changes
Able to produce offspring
Increase size or change in life stage
Disposal of wastes from the body
Making or acquiring food
How does the photosynthesis process work?
Photosynthesis is the process occurring in the chloroplast where plants make glucose sugars from water and carbon dioxide using solar energy; solar energy is changed into chemical energy.
Plants using sunlight to synthesise nutrients from carbon dioxide and water.
What is the word equation of photosynthesis?
Carbon dioxide + water =(light energy + chlorophyll)= glucose + oxygen
How do you speed up photosynthesis?
Increase light, increase concentration of CO2, and increase temperature.
Food is taken into the mouth.
Food is broken down by a physical force and enzymes.
Small particles pass into the blood capillaries.
Small food enters cells and used for cellular processes
Undigested food which is not used leaves the anus as faeces.
What are the two types of digestion and explain them.
Mechanical is when the shape is physically changed so it can fit through the small diameter of the digestive system
Chemical is when the bonds are broken and this allows useful chemicals to be released and dissolved in the blood
What is chlorophyll?
Chemical in chloroplasts responsible for absorption of sunlight, appears as a green pigment in leaves.
Define life process?
The process of MRS C GREN carried out by all living organisms.
Define organelle and explain its use.
Parts of a cell that have specific functions.
The storage of sugar in a plant.
Small projections in the small intestine that increase the surface area for absorption.
Small blood vessels that deliver nutrients, and remove waste from individual cells
Recite MRS C GREEN
Movement, respiration, sensitivity, cells, growth, reproduction, excretion, nutrition.
What is the word equation for respiration?
glucose + oxygen = carbon dioxide + water
Label a plant cell
Label an animal cell.
Label a plant
Label a leaf cross section
Label the digestive system.
Label a microscope
What is the main function of the small intestine?
The main function is to absorb minerals and nutrients from food
