Which of the following is a cellular organelle found in all plants a) capsulesb) plastidc) rhizoidsd) spore
B) plastid
The correct answer is (b) plastid.
Plastids are a group of membrane-bound organelles found in plant cells that are involved in various cellular functions, including photosynthesis and the synthesis and storage of important biomolecules such as lipids, starches, and pigments. Chloroplasts, which are a type of plastid, are responsible for photosynthesis and giving plants their green color. Other types of plastids include chromoplasts, which are responsible for the synthesis and storage of pigments, and leucoplasts, which are involved in the synthesis and storage of starches and lipids.
Capsules are structures found in certain bacteria and fungi that help protect the cell and allow for attachment to surfaces. Rhizoids are root-like structures found in some fungi and non-vascular plants that help anchor the organism to a substrate and absorb nutrients. Spores are reproductive structures found in many types of organisms, including plants, fungi, and bacteria.
