Answer:
cell membrane
mitochondria
lysosomes
ribosomes
Explanation:
Cell membrane is the boundary of animal cell which is responsible for the intake of nutrients from outside environment of the cell. Cell membrane is a semipermeable membrane which take nutrient through a process of diffusion and active transport. Mitochondria is also called power house of the cell in which glucose molecule is broken down and energy is released. Lysosomes is an important organelle of the cell which is responsible for the collecting and removal of waste material from the cell through cell membrane. Ribosomes helps in the production of proteins and enzymes needed by the cell for different activities.
Different colored bands in each solvent signify the different materials that are found in the substance that is been analysed.
The green band in the solvent represent the green chlorophyll which are found in leaves. Chlorophyll is the substance which gives the plants the capacity to trap energy from the sun for production of food.
Answer:
Permeable membranes allow anything to pass through.
Impermeable membranes have a poor permeable rate or nothing can pass through.
Semipermeable membranes select or allow only certain substances to pass through.
Explanation:
Permeable Membranes:
- Window screen - can pass water and air through 100%
- Mesh - can pass water and air through 100%
Impermeable Membranes:
- Clay - permeability rate is extremely low, and water cannot pass through
- Ziplock bag - nothing can come in or out
Semipermeable Membranes:
- Plant and Animal cell membranes (lipid bilayer) - only certain substances can pass through, like soluble vitamins
- Cell Organelle Membranes - only certain substances can pass through the mitochondria, for example
