Plant Cell Structures and Functions

Cell wall = Provides support and shape to plant cells Cytoplasm = Contains ground plasm and the cell membrane Cell membrane = Envelops the cell and controls substance passage Chloroplasts = Responsible for photosynthesis

Ground plasm = Liquid contents with dissolved salts and gases Cell membrane = Selectively permeable and controls substance passage Chloroplasts = Contain chlorophyll for trapping radiant energy Cell wall = Formed outside the cell membrane and made of cellulose fibers

Chemical processes take place in this part of the cell: = Ground plasm Responsible for converting radiant energy to chemical potential energy: = Chloroplasts Only found in plant cells and provides support: = Cell wall Envelops the cell and is selectively permeable: = Cell membrane

<p>Mitochondria = Known as the 'powerhouse' of the cell Vacuoles = Play a role in nutrition and osmoregulation Nucleus = Contains nucleoplasm and nucleolus, where genetic information is stored Prokaryotic cells = Do not have a nucleus or any cellular bodies</p> Signup and view all the answers

<p>Cellular respiration = Gradual release of energy from energy-rich fuel molecules like glucose Turgor pressure = Pressure inside plant cells due to water in vacuoles DNA = Molecule carrying genetic information used in living organisms Gene = Smallest unit of genetic material carrying code for specific characteristics</p> Signup and view all the answers

<p>Turgid cell = Cell swells up due to water entering via osmosis Flaccid cell = Cell loses shape as water is lost, decreasing turgor pressure Eukaryotic cells = Contain a nucleus that encases DNA and various organelles Chromosomes = Long structures within cells usually visible as a chromatin network</p> Signup and view all the answers
