  Answer   Erythropoiesis is the process by which red blood cells (erythrocytes) are produced. In human adults, this usually occurs within the bone marrow. In huma â¦ ns with certain diseases and in some animals, erythropoeiesis also occurs outside the bone marrow, within the spleen or liver.
All plants use photosynthesis as a means of food production. They also all have their cells surrounded by cell walls in place of cell membranes. Plants also have large vacuole â¦ s in their cells, and all of them have chloroplasts (which is what makes them green).n addition, they all have body plans that include leaves, stems, and roots. Most seed plants live on land. Seed plants f â¦ ace many challenges, including standing upright and supplying all their cells with water and food. They meet these two challenges with vascular tissue.
Among the features that distinguish plant cells from animal cells is the vacuole, a large membrane-enveloped sac found in cells of plants but not animals. Young plant cells often have more than one vacuole, but these vacuoles fuse to form a single organelle as the cell grows.mong the features that distinguish plant cells from animal cells is the vacuole, a large membrane-enveloped sac found in cells of plants but not animals.
