These two systems work together to bring oxygen to the cells

respiratory and circulatory

These two systems work together to bring glucose to the cells

digestive and circulatory

This system controls the movement of blood through the human body

Circulatory system

This system controls the absorption and digestion of food

Digestive system

This system is responsible for stability and movement of human body.

Musculoskeletal system

This system brings oxygen into the body and expels carbon dioxide

Respiratory system

This system sends messages between the brain and body

Nervous

Groups of cells that have a similar structure and that function together.

Tissues

What are the four types of tissue?

Nervous, muscle, connective, epithelial

Write the order of cell organization from smallest to largest

cell, tissue, organs, organ system

This provides support for the internal structures of the cell. It contains the cell's organelles.

Cytoplasm

This organelle produce energy necessary for the cell’s survival and functioning. The energy is converted from glucose into ATP (adenosine triphosphate) which is usable energy.

Mitochondria

This organelle is a large membrane in the cell that is filled with fluid. It helps maintain the shape of the cell.

Vacuole

These organelles contain chlorophyll, which is required for photosynthesis.

Chloroplasts

A rigid layer with the primary purpose of protecting and providing support for the cell.

Cell wall

This is a barrier around the cell. It is semi-permeable, meaning that it allows some things to enter the cell while other things are excluded. It's role is to control the entry and exit of various substances in the cell.

Cell membrane

This organelle is a network of bubbles and tubes that are either rough or smooth. It helps to modify and transport proteins.

Endoplasmic reticulum

This organelle sorts important proteins and fats in the cell before they are delivered to their next destination.

Golgi apparatus

These organelles are the smallest in the cell and create proteins, often referred to as protein factories

Ribosomes

This organelle is responsible for making ribosomes.

Nucleolus

This organelle is the control centre of the cell. The nucleus also stores DNA and genetic information required for cell division and growth.

Nucleus

Give three differences between a plant cell and an animal cell

chloroplasts, large vacuole, cell wall

An organism that is made of more than one cell, with groups of cells taking on different specialized functions.

Multicellular

An organism that is made up of only one cell that carries out all the functions needed by the organism.

Unicellular

Objective Magnification × Eyepiece Magnification =

Total Magnification

The fine adjustment knob sharpens the view of the specimen. This is the only adjustment knob needed while using the high power lenses.

Fine adjustment knob

These are used to magnify the specimen in low power (4x), medium power (10x) and high power (40x).

Objectives Lens

A lens that magnifies the specimen. It typically magnifies by 10 times.

Eyepiece

The stage is the location where the slide is placed for observing.

Stage

The ideas that: All living things are made up of cells, cells are the basic units of life, and all cells are created from existing cells is referred to as..

The Cell Theory

The basic structural unit of an organism.

Cell

Far sighted vision is corrected with what type of lens?

Convex

Near sighted vision problems is corrected with what type of lens?

Concave

Place the electromagnetic spectrum from longest to shortest wavelength.

Radio, microwave, infrared, visible, UV, x-ray, gamma

If a light ray passes from air into glass at an angle, what happens to the refracted light ray?

It bends toward the normal.

If the angle of incidence measures 55 degrees, what is the angle of reflection?

55 degrees

Cone cells found in the retina are used to detect what?

Coloured light

The part of the eye where the light is focused to form an image?

Retina

The part of the eye that refracts the most light entering the eye?

Cornea

This colour is made from the combination of blue light and red light

Magenta

What is the name of the ray that is bouncing off the mirror in ray in a reflection model?

reflected ray

What is the name of the incoming ray in a reflection model?

Incident ray

This image is produced from sight lines (or extended rays)

Virtual image

The property of light that describes the fact that light travels in straight lines.

Rectilinear Propagation

A material that allows light to pass through unaffected, an object appears clear through it.

Transparent

A material that allows light to pass through but scatters it in the process, an object appears fuzzy through it.

Translucent

A material that prevents visible light from passing through it, an object cannot be seen through such a medium

opaque

The type of reflection that produces a blurry image of the surroundings

Diffuse reflection

The type of reflection that produces a clear image of the surroundings

Specular reflection

Identify B.

What will happen when white light passes through yellow glass.

Red and green light pass through and the others are absorbed.

What is a risk of overexposure to x-rays?

Could develop cancer

What is one positive use for x-rays?

Identifying bone fractures or breaks

What is the frequency of a wave that passes a point 18 times in 2 seconds.

9 Hertz

What is the acronym that can help you remember the order of the visible spectrum?

ROY G BIV

The height of the wave from the rest position is called

Amplitude

What type of electromagnetic radiation has the longest wavelength?

Radio waves

What type of electromagnetic radiation has the shortest wavelength?

Gamma rays

What do you get if you combine all the colours in the visible light spectrum?

White light

A shirt appears blue on a bright sunny day because?

The shirt reflects blue light

What colour has the longest wavelength, or the lowest frequency?
