Revision:
- What is a cell? How it is related to all organisms? The building blocks of life.
- Draw a typical cell and label it.
- Differentiate between plant cell and animal cell. Plant cells can be larger than animal cells. Although plant and animal cells have many similarities, plant cells have vacuoles, a cell wall and chloroplasts.
- Write the functions of cell wall, cell membrane, cytoplasm, mitochondria, vacuole, chromosomes and gene.
Cell Wall - Provides Strength for the plant.
Cell Membrane - Hold everything inside and controls what comes in and out.
Cytoplasm - Holds the cell organelles and contain nutrients and chemical.
Mitochondria - Holds out respiration to give the cell energy.
Vacuole - Helps keep the cell firm.
Chromosomes - A thread-like structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
Gene - A unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
- Define Photosynthesis and explain the process. Give chemical and word equation. Photosynthesis is a process in which plants prepare their food in the presence of sunlight, by taking carbon dioxide from the environment and water from the Earth.
Equation:
- Define Respiration and explain the process. Give Chemical and word Equation. Respiration is the process that the body uses to relate energy from digested food(glucose).
