Eukaryotic cells are complex in structure, with a membrane-bound nucleus and many functioning organelles that undergo specific jobs for the cell.Answer and Explanation: Plant and animal cells differ in some of their major structures and organelles. Plant cells have a rigid, firm cell wall that en...

- Both animal cells and plant cells are eukaryotic cells, meaning they have a defined nucleus and organelles. 3. Examine Plant Cells: - Plant cells have a cell wall, which provides structure and protection. - Plant cells contain plastids (like chloroplasts), which are involved in photosynthesis...
Plastids are the double-membrane organelle found in the cells of plants and are the main sites of photosynthesis in all eukaryotic cells. There are four main types of plastids.
At the apex of the tube are active ribosomes andendoplasmic reticulum(types of cellorganelles) involved inproteinsynthesis. Pectinase and a glucanase (bothenzymesthat break downcarbohydrates) probably maintain flexibility of the growing tube and aid in penetration. The pollen tube apex also releases ...
How is biology used in plant biology? What is the function of the coded instructions contained in the body cells of an organism? How do autotrophs make food? What are the different organelles that make up our cells? What are their functions?
cells, it is thought they came into existence first. The currently accepted theory of cell evolution is called theEndosymbioticTheory. It asserts that some of the organelles, namely the mitochondria and chloroplast, were originally smaller prokaryotic cells engulfed by larger prokaryotic cells....
Cells in humans and animals vary greatly in size. The smallest cells in the human body are sperm cells and the granule cell of the cerebellum. Some neurons, or nerve cells, may grow as long as several feet long and extend from the limbs to thespinal cordto the brain. ...
The vacuoles in plant cells are larger than those in the animal cells. Why are lysosomes called suicidal bags? Why are lysosomes known as 'suicide-bags' of a cell? Lysosomes are the organelles that have digestive enzymes. When lysosomes burst, the digestive enzymes released start digesting its...
How are organelles in cell-like organs in a human body? What are the main differences between plant cells and animal cells? Which part of a cell provides structure and gives it its shape? What are the main structures within the cell nucleus? What are the three parts of the ...
