Microscopes, Cell Theory, and Key Players
This Dutch scientists is credited as the first person to observe living microorganisms under a microscope.
Antonie Van Leeuwenhoek
These are the two main types of cells classified based on structure and organization.
Prokaryotic and Eukaryotic
This is the movement of substances across a cell membrane without the use of energy.
Passive transport
These are substances in food that the body needs to energy, growth, and life functions.
Nutrients
This green pigment inside chloroplasts absorbs light energy for photosynthesis.
Chlorophyll
This is the process in which plants create their own food.
Photosynthesis
This Dutch lens maker is credited with building one of the first compound microscopes around 1590.
Zacharias Jansen
This organelle controls what enters and leaves the cell.
Cell membrane
This process specifically refers to the movement of water molecules across selectively permeable membrane.
Osmosis
These are the six essential nutrient groups the human body needs to function properly.
-Carbohydrates
-Proteins
-Fats
-Vitamins
-Minerals
-Water
This structure is leaves opens and closes to regulate gas exchange and water loss.
Stomata
These are the 7 life functions shared by plants and animals that are necessary for survival and maintaining life.
Transportation, Nutrition, Growth & Repair, Reproduction, Regulation, Metabolism, Synthesis
What are the three main statements of cell theory?
- All living things are made of cells
- Cells are the basic unit of life
- All cells come from pre-existing cells
This organelle is responsible for making proteins and can be found free in the cytoplasm or attached to the rough endoplasmic reticulum
Ribosomes
This process allows a cell to remove waste or release large molecules by fusing vesicles with the cell membrane and pushing materials out of the cell.
Exocytosis
This is the Canada's Food Guide recommendation for how your plate should be divided for a balanced diet. (Include a drink)
- 1/2 fruits and vegetables
- 1/4 protein foods
- 1/4 whole grains
- Water as a drink
This vascular tissue carries sugars made during photosynthesis throughout the plant
Phloem
These are the two types of digestion the body does to break food down into essential nutrients.
Chemical and Mechanical Digestion
This type of microscope uses electrons instead of light, allowing it to produce much higher resolution images because electrons have a shorter wavelength than visible light.
Transmission Electron Microscope
This organelle modifies, packages, and transports proteins and lipids throughout the cell.
Golgi apparatus
Cell membranes are composed of these 2 materials.
Phospholipid bilayer and Proteins
This is the process by which the body maintains a stable internal environment despite external changes.
Homeostasis
This pressure builds inside guard cells when water enters, causing stomata to open.
Turgor Pressure
The typical heart rate and blood pressure of an average teen is:
Heart rate = 60-100 beats per minute
Blood pressure = 120/80
These two biological entities are considered exceptions to cell theory because they are not made of cells and require a host to reproduce.
Viruses and Prions
This organelle is responsible for producing ATP, which is the usable energy form of the cell, through cellular respiration.
Mitochondria
A plant cell is placed in a solution where the solute concentration outside the cell is higher than inside. Water leaves the cell, and the cell begins to shrink. What type of solution is this?
Hypertonic solution
This part of the digestive system is where 80-90% of nutrient absorption occurs using villi to move digested nutrients into the bloodstream.
Small intestine
This theory explains water movement through a plant driven by evaporation, transpiration, cohesion, and adhesion.
Cohesion-adhesion theory
These are ALL parts of the circulatory system.
1. Heart
2. Blood vessels - Arteries, Veins, Capillaries
3. Components - Red/ White blood cells, Plasma, Platelets.
