Plant Cells
What is a plant Cell?
The basic structural and functional unit of plants, acting as a eukaryotic cell with a defined nucleus and membrane-bound organelles
What is an Animal Cell?
A type of eukaryotic cell that forms the fundamental, structural, and functional units of all living organisms in the kingdom Animalia
What is an ecosystem?
An ecosystem is a community of living organisms (plants, animals, microbes) interacting with their physical environment (air, water, soil). It is a system composed of both living (biotic) and non-living (abiotic) factors
What are the main parts of a plant?
The shoot system (above ground: stems, leaves, flowers) and root system (below ground)
What is the function of a ribosome?
What is the function of a ribosome?
What is the purpose of the plant cell wall?
The rigid cell wall is composed of cellulose, hemicellulose, and pectin, providing shape, structural support, and protection to the cell.
What are the primary components of an animal cell?
They consist of a Nucleus (genetic material), Cytoplasm (gel-like substance), Cell Membrane (protective barrier), Mitochondria (powerhouse), Ribosomes (protein synthesis), Golgi Apparatus (packaging), Lysosomes (waste breakdown), and Endoplasmic Reticulum (transport)
What are biotic and abiotic factors?
What do plant cells have that animal cells do not?
A rigid cell wall, chloroplasts for photosynthesis, and a large central vacuole for water storage
What is the "powerhouse" of the cell?
The mitochondria, which produce energy in the form of ATP.
What is the main function of the chloroplast?
Chloroplasts contain chlorophyll, which captures sunlight to produce food (glucose) via photosynthesis
What is the function of the mitochondria?
Mitochondria produce energy (ATP) through cellular respiration, often referred to as the powerhouse of the cell
What are the main types of interactions in an ecosystem?
Predation ,Competition, Symbiosis, Mutualism,
Commensalism ,Parasitism
What is the function of the root hair cell?
They have an elongated shape that increases surface area for absorbing water and mineral salts from the soil
What does a plant cell have that an animal cell does not?
A rigid cell wall, chloroplasts (for photosynthesis), and large vacuoles.
What is the function of the large central vacuole?
The vacuole stores water, nutrients, and waste materials, while also creating turgor pressure to keep the cell rigid
What is the role of the cell membrane?
It is a thin, semi-permeable lipid layer that protects the cell and controls what enters and leaves.
What are the ecological levels of organization?
The hierarchy goes: Organism Population Community Ecosystem Biome Biosphere
How do animals cells get energy?
Unlike plants that produce food (photosynthesis), animals consume other organisms, breaking down food in the stomach for energy.
Which organelle acts as a, "garbage disposal"?
Lysosomes, which break down waste and used materials.
How do plant cells differ from animal cells?
Plant cells have a cell wall, chloroplasts, and a large central vacuole, which are absent in animal cells.
How do animal cells differ from plant cells?
Animal cells lack cell walls and chloroplasts, have irregular shapes, and possess centrioles, whereas plant cells have rigid cell walls and chloroplasts for photosynthesis
How do organisms interact with their environment?
Organisms interact by competing for resources, forming symbiotic relationships, and adapting to abiotic conditions like temperature and moisture. Changes in these conditions (like climate changes) require organisms to adapt or face survival challenges
What allows plants and animals to thrive?
Adaptations, which are unique structures (like feathers) or behaviors (like migration) that help them survive in their environment
What is the function of the cell membrane?
It surrounds the cell, controlling what enters and exits.
