Cells

serves both as the repository of genetic information and as the cell's control center.

provids strength and structure for cell, also gives semi-pemuble surface for things to pass.

the cell membraine is to protect the cell from its surroundings

Transfers water,glucose, oxgen and protins

using photosynthesis it absorbs energy from the sun.

To store food, waste and water for cells.

Small structure that synthesizes proteins.

thsi is for cell shape, material transport like genetic material and products for cellular respiration, and storage

this acts as a barrier that separates the contents of the nucleus from the cytoplasm.

examples specialized cells in the human body:Blood cells, surface skin cells, Bone cells, Epithelial cells, Neurons, Cardiac muscle cells, Skeletal muscle cells,

organ systems in the human body

Skeletal system:gives the body structure and protects organs.

Muscular System: Suports the body and helps it move.

Digestive system: Breaks down food and absorbs nutrients.

Circulatory system: Helps to move nutrients and waste products into and out of your body.

Epithelial tissue: The layer of cells on the outside and inner body surfaces.

Connective tissues: Bones and cartilage.

Muscle Tissue: Made of cells that can get contract and helps your body to move.

Nervous Tissue: made of netrons cells that can send messages to many parts of the body. That includes the brain.

Cells: cells are the basic building blocks if life. Cells can specialize and be different from each other.

Tissue: A tissue is a group of cells that have a similar function. they do the same job. For example, the lens in your eye.

Organs: Organs are structures that are made of two or more types of tissues working together to do a job. For example, your eye is an organ that has cells in the lens, it also has nerve cells and muscle cells to help it function properly.

Organ systems: Organ systems are made up of two or more different organs working together to do different jobs.

Animal and Plants are made out of cells, even you are made
of cells. Some orgnisams can even be only one cell.

Cells are the building blocks of living things, with different cells possessing unique organelles that enable them to perform specific functions.

In all living things, cells divide, or produce duplicates of themselves. Cells do not appear out of thin air.

How unicellular organisms eat their prey: An amoeba captures prey by stretching pseudopods from its membrane, wrapping them around the prey, creating a vacuole inside, and introducing enzymes to break down the prey.

how multicellular organisms are different from unicellular organisms, and what advantages or disadvantages they have:Multicellular organisms have specialized cells that enable them to have diverse tissues, become more complex, and grow larger. They can lose cells without dying. Unlike unicellular organisms which are limited to organelles in one cell and can die if the cell membrane is damaged however they are more simple.

dynamic equilibrium: When Diffusion happens, the particle will continue mixing until it reaches dynamic equilibrium. dynamic equilibrium is when 2 sides are equal. even though it is equal, the particles will still moving,however the concentration will remain around the same .

some examples: spraying perfume into the air, scented candles, the smell of cooking spreading through the house, a drop of food colouring spreading in water. In all particles are mixing with the particles around it.

Solvent and solute: This is when Water molecules travel over a semi-permeable membrane, moves them from an area of low solute concentration to one of high solute concentration.
