Explanation:
Cell wall and Chloroplast-A chloroplast is an organelle that is only present in plant cells. It is a plastid that contains chlorophyll and is also where photosynthesis takes place.
Human hair-Function. Root hairs are where most water absorption happens. They are long and so they can penetrate between soil particles, and prevent harmful bacterial organisms from entering the plant through the xylem vessels. ... As root hair cells do not carry out photosynthesis, they do not contain chloroplasts.
Vacuoles-A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
Mitochondria-Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.
Cell wall-In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape.
Ribosomes-ribosomes
During protein synthesis, ribosomes assemble amino acids into proteins. Ribosomes are the cellular structures responsible for protein synthesis. When viewed through an electron microscope, ribosomes appear either as clusters (polyribosomes) or single, tiny dots that float freely in the cytoplasm.
Endoplasmic reticulum-ENDOPLASMIC RETICULUM is a network of connected membrane tubes. Thus the rough E.R. and the Golgi apparatus and vesicles are part of the cell's highway system because they are involved in moving proteins around the cell and to the outside of the cell.
