Cells of animals, plants, microscopes, fertilization and reproduction Flashcards
Name the parts of a microscope
Eyepiece,body tube, head, revolving nose piece,arm,stage,mechanical stage,stage clips, diaphragm, adjustment knob,light source, fine adjustment knob, base.
What are a cell’s vital functions?
survive: feeding, digesting, producing energy through respiration, creating useful substances, eliminating waste, multiplying and dying.
similarities of a plant and animal cell
Cell Membrane,Nucleus,Cytoplasm,Mitochondria
differences of a plant and animal cell
Wall, chloroplasts, shape.
What part of the plant cell is responsible for photosynthesis?
The chloroplast is responsible for photosynthesis in plant cells.
What organelle is found in both plant and animal cells and is responsible for energy production?
The mitochondria are responsible for energy production in both plant and animal cells.
What is the function of the vacuole in plant cells?
The vacuole stores water and helps maintain the cell’s shape and turgidity in plant cells.
Do animal cells have a cell wall?
No, animal cells do not have a cell wall. They only have a cell membrane.
What is a key advantage of asexual reproduction?
Asexual reproduction allows for rapid reproduction with only one parent, producing genetically identical offspring.
How is sexual reproduction different from asexual reproduction?
Sexual reproduction involves two parents and produces genetically diverse offspring, while asexual reproduction involves one parent and produces genetically identical offspring.
What is the role of fertilization in sexual reproduction?
Fertilization is the process where a sperm cell and an egg cell combine to form a zygote, beginning the development of a new organism.
Where does internal fertilization occur?
Internal fertilization occurs inside the female’s body, where the sperm fertilizes the egg.
In which environment does external fertilisation typically happen?
External fertilization typically happens in water, where eggs and sperm meet outside the female’s body.
Which type of fertilisation generally requires fewer offspring but provides more protection?
Internal fertilization typically produces fewer offspring but offers more protection to the developing embryos.
What part of the microscope is used to focus on a specimen?
The coarse adjustment knob is used for large focusing adjustments, and the fine adjustment knob is used for smaller, detailed adjustments.
