Exam 1 - Life Processes, Cells, Kingdoms And Magnification Flashcards
What does MRS GRENC stand for?
Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition and Control
Which life process involves the intake of nutrients for energy and growth?
Nutrition
Which life process involves the removal of waste products from an organism?
Excretion
Which life process involves the ability of an organism to detect and respond to stimuli?
Sensitivity
Which life process involves the production of new individuals of the same species?
Reproduction
Which life process involves the release of energy from food?
Respiration
True or False: Movement is a life process that is exclusive to animals.
False
Which life process describes a kitten growing into a cat, or a child growing into an adult?
Growth
Which life process involves the physical change in position of an organism?
Movement
Which life process involves the conversion of oxygen and glucose into energy?
Respiration
Give an example of Nutrition
Starch is produced in photosynthesis in plants
Give an example of excretion
Breathing out carbon dioxide
Give an example of control
Keeping body temperature at a constant level
Give an example of sensitivity?
Removing your hand from a hot surface
Give an example of Respiration
Aerobic uses oxygen, and anaerobic doesn’t use oxygen
Label an animal cell
GO TO GOODNOTES
Name all the main parts of an Animal Cell
- cell membrane
- ribosomes
- Mitochondria
- nucleus
- cytoplasm
What is the function of cytoplasm in an animal cell
It is the site of chemical reactions in the cell
What is the function of the cell membrane
It controls the entry and exit of of substances
What is the function of the nucleus
It controls the activities of the cell, and holds the DNA
What is the function of the mitochondria
To release energy through respiration (a chemical reaction)
What is the function of ribosomes
To make proteins (protein synthesis)
What is the function of ribosomes
To make proteins (protein synthesis)
Label a plant cell diagram
GO TO GOODNOTES
Name all the main parts of a plant cell
- cytoplasm
- nucleus
- cell membrane
- cell wall
- mitochondria
- permanent vacuole
- chloroplasts
What is the function of the permanent vacuole
Contains cell sap which has dissolved sugar, mineral ions and other solutes. The permanent vacuole shapes the cell.
What is the function of chloroplasts
Chloroplasts are where photosynthesis occurs. Chloroplasts contain chlorophyll.
What is the function of a cell wall
To provide structure and protection for the cell
Label a fungi cell diagram
GO TO GOODNOTES
How do fungi get nutrition
Saprotrophic nutrition - fungi secrete enzymes onto their food, and the enzymes break down the food into molecules, which the fungi absorb.
What are the main units of measurement
Metre
Millimetre
Micrometre
Nanometre
Draw out the diagram of measurements
GO TO GOODNOTES
Name all the parts of a microscope
Eyepiece
Course focus wheel
Fine focus wheel
Objective lens
Stage
Glass slide
Light source
Condenser and Diaphragm
Base
Label a microscope
LOOK ON GOODNOTES
Function of the eyepiece
For the viewer to look through
Function of the coarse focusing wheel
To get the slide into focus on a lower magnification
Function of the fine focusing wheel
O sharpen focus, at a higher magnification
Function of the objective lens
Selectable lenses that magnify the object
Function of the base
To keep the microscope stable
Function of the stage
The platform to place the glass slide on
Function of the diaphragm and condenser
To focus light on the part of the slide being studied
Equation for magnification
Magnification = image size / actual size
