Plant roots absorb ammonium ions and nitrate ions for use in making molecules such as DNA,amino acids, and proteins. ... The chemical process by which atmospheric nitrogen is fixed by bacteria into organic compounds that can be readily used by plants
scientists draw about their experiment. Conclusions must be based on evidence-(observations and data that make you believe something is true). Scientist use their observations to draw a conclusion. They summarize what they have learned by analyzing their observations.
Pressed? what subject is this
Answer: 1 Lysosomes and peroxisomes, Microtubules, Endoplasmic reticulum, Mitochondria
2 The role of the nucleus of a eukaryotic cell is to control the cell. Because it contains most of the cell's DNA, which is encoded with genetic instructions, the nucleus controls which proteins the cell makes.
3 The rough endoplasmic reticulum has ribosomes on its surface. This is what give the RER a "rough" appearance. The smooth endoplasmic reticulum (SER) does not contain ribosomes. The Smooth ER looks more like tubes. The SER helps in the storage of proteins and lipids.
4 Secretory vesicles contain materials that are to be excreted from the cell, such as wastes or hormones.
Transport vesicles move molecules within the cells.
Vacuoles are vesicles that contain mostly water.
