What do human skin cells do?

They make up the largest organ in the human body. Their function is to act as protection and gatekeepers

what do human bone cells do?

Human bone cells make up the structure that supports the body. Human bone cells make up the bones

What do human muscle cells do?

Human muscle cells transform more energy because thats what they specialize in. They have more mitochondria than any other cell

What do human nerve cells do?

Human nerve cells transmit electrical impulses along pathways to the brain

What do human brain cells do?

Human brain cells receive and transmit electrical impulses

What do human eye cells do?

They have special cells that detect light

What do human blood cells do?

Human blood cells transport oxygen and carry away wastes of cellular processes

What do human fat cells do?

Human fat cells keep unused energy in the form of fat, to be released and burned when needed

What do leaf cells do?

Leaf cells transform the suns energy into sugars with the help of photosynthesis and chloroplasts

What do stem cells do?

The stem cells transport water and materials such as food and water throughout the plant

What do the root cells do?

The root cells absorb water and nutrients from the soil and transport these resources to the stem

Whats a decomposer?

An organism that decomposes organic material

What is diffusion?

The process of particles moving from an area of a higher concentration of particles to a lower concentration of particles

what is osmosis?

The diffusion of water (Movement of water from an area of high concentration to an area of lower concentration)

Give 3 examples of unicellular organisms?

1. E. coli


2. phytoplankton


3. amoeba

Give examples on how unicellular organisms move?

1. Flagella (act as an oar and "swims" through the water)


2. pseudopodia (feet like appendages)


3. Cilia (hair like strands that act like tiny limbs)



Why are multicellular organisms specialized?

A multicellular organism has specialized cells that perform specific functions

Why are cells small in size?

smaller sized cells perform different processes more quickly

What are examples of decomposers?

1. Fungi


2. Bacteria

what are types of cellular processes?

1. Cellular reproduction (mitosis)


2. cellular respiration


3. Cellular transportation



what is cellular respiration? what materials are involved?

Cellular respiration is the transformation of energy from sugar in food into energy to grow and live.


materials:


Sugar + oxygen -> energy + carbon dioxide + water




SOECW

What is photosynthesis? what are materials are involved?

Photosynthesis is when chloroplasts produce the sugar needed by the mitochondria.


Materials:


Carbon dioxide + water + sunlight -> sugar + oxygen

Whats the difference between animal and plant cell division?

Animal cells pinch in half whereas in a plant cell a new cell plate develops across the cell to create a new cell wall between the two nuclei.
