1: plant cells have a cell wall and also have a cell organelle called chloroplasts. Cell wall provides the structure for a plant because it doesn’t have bones like animals do, and chloroplast help make it food through photosynthesis. 2: the cell membrane in both plant And animal cells helps lets needed materials in for the cell (plant: lets in water, and co2) (animal: lets in other materials), cell wall provides structure to a plant cell, but animals don’t have it because we have bones. Nucleus in both plant a animal cells help control the organelles and make them function properly, cytoplasm in both plant and animal cells helps hold all the organelles of the cells in place and lets materials travel around the cell to where it’s needed. The mitochondria help provide both an animal and plant cel energy for its everyday processes and is needed for the organelles to function properly. The chloroplasts which are only in plant cells, helps the plant make food for itself whereas we can shut get our nutrients by getting up and getting/eating food. Finally, vacuoles in both plant and animal cells helps hold food and other materials for the cells but mainly in plant cells where the vacuoles are bigger and are needed to hold much of the extra water for when the cell needs it.
1.Plant cells have a cell wall, but animals cells do not. Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not. ... Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.
An axis is an invisible line around which an object rotates, or spins. The object can be a tiny particle, smaller than a single atom. Or it could be a star with the mass of a thousand suns.
mtDNA is inherited from the mother of a child, this is because mitochondria are in the cytoplasm and the father's gamete (sperm cell) contributes very little or no cytoplasm to the zygote. We know that mitochondrial Eve came from Africa because the mutations in the mtDNA occurred before the <em>out-of-Africa dispersal</em>.
