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. |
