1.Bone cells(Osteocytes) They are the toughest body Cell as they are bound together by calcium and phosphate. As you knows they give strength, support and frame-work to the body by enclosing organs in skeletal system i.e bones.
2. Cartilage cells(chondrocytes)- These cells are similar to bone cells but the surrounding material is just loose and flexible compared to those of bone cells. Hence they are freely bendable. They are present in ear bone (hence ears are fold-able), in between large bones to help them bend and move freely like in between two ribs, spinal bones, joints etc.
3. Nerve cells: These cells are very long and have many branching at either ends. Their specialty is they never multiply in one's life time.They are present all over the body and are sometimes as long as few meters long. They are human brain cells and are found in plenty in brain and the spinal cord and form the nervous tissue.

4. Epithelial cell: These cells are very simple cells which form covering of other cells. These cells form covering layers of all the organs and hence are preset in skin, scalp, respiratory tract, in the buccal cavity surface etc. Ex: Skin cells, mucous cells.
5.Muscle cells: These cells are of muscle tissue mostly long, large and have ability to contract and relax providing movements. They are three types as skeletal, cardiac and smooth muscles.
- Skeletal muscles cells are attached to long bones and assist in their movement (by muscle contraction).
- Cardiac muscles cells are present only in heart muscle and responsible for heart beats.

- Smooth muscle cells are flexible yet, can contract and relax and are present in stomach, intestine, blood vessel walls (vascular tissue) etc. helping in movement of food through the gut.

6 Secretory cell: These cells as name indicates are secretory in nature. They form glands and secrete something important ex; pancreatic cells which secrete insulin, glucagon, salivary gland secrete salivary amylase, sebaceous gland secrete oil on the skin etc.They are found in all secretory organs.
7.Adipose cells: These are fat cells and are storage in nature to store fat. Especially seen in the soles, palms, bums etc. They reduce friction to the body.
8. Blood cells: These cells include RBC's, WBC, Thormbocytes etc. They are always motile and never stay in one place. They have limited life span and they never multiply to form new cells. instead new cells are formed from other cells.

How do cells make and use energy?
Cells make and use energy through the process of photosynthesis. This process both creates energy and uses energy to deliver the nutrients.
How are the actions of the forklifts related to actions in cells?
The forklift uses a battery and the cells need energy.
What uses energy to take particles into the cells?
Endocytosis, hope this helps!
What are the four characteristics of life?
Consumes, reproduces, contains one or more cells, and uses energy.
Where does a muscle receive the energy from to contact?
What we call a muscle is really a large number of cells that work by contracting. Work that all cells do uses glucose, a simple sugar. This is used in producing ATP the "battery" that generates energy for the cells,
Copmpared to other body cells a muscle cell is likely to have more of what organelles for energy?
Mitochondria. Muscle cells need more energy over a short period of exercise than most other cells. The cell uses mitochondria to transform food energy into a energy source it can use for its reactions.
What is the energy source of the flu virus?
The flu virus is a non-living thing, so it doesn't have its own energy source. To reproduce, it hijacks the cells of a living being, such as the upper respiratory cells of a human, and uses the energy of those cells to make more copies of itself.
How do organisms use up energy?
The process of living uses energy, eating, hunting, keeping warm, making new cells etc.
Can you compare chloroplast with a softball game?
A chloroplast creates energy in cells from sunlight and a softball game is played in the sun usually, and uses energy?
What does chlorolplast do?
Chloroplast in plant cells absorbs the sun's energy and uses it for photosynthesis to produce sugar and oxygen.
What happens to plant cells in the second stage of photosynthesis?
The cell uses captured energy to make sugars.
What creates the energy used in photosynthesis?
The sunlight the chloroplast in the plant cells capture. The chloroplast first gets the sunlight. Then, it uses other stuff like CO2 and water to create the energy that the plant uses.
