BOT 2100 Lecture Notes - Lecture 6: Carotenoid, Phloem, Sclereid
Document Summary
Many plants in dry climates have hairy leaves to reduce water loss: reducing high light intensity inner membrane of plastids contains the bulkier parts of the cell. A lot of import and metabolic export between plastids. Membrane around the plastid has a lot of transporter. A lot of chloroplast in leaf cells other plastids varies on metabolic processes of the plant. All carbon fixation occurs in the chloroplast. Plasterblobules sacs of lipid miniature organelles within an organelle thylakoid sa(cid:272) like (cid:373)e(cid:373)(cid:271)ra(cid:374)e that"s hollow with protei(cid:374) i(cid:374) it absorbs red and blue light: contain proteins, houses machinery for antioxidant. 3 principal categories: chloroplasts - photosynthesis chromoplasts - colour (reds, yellows - carotenoid pigments) leucoplasts - colourless, storage of starch, oils. Dermal tissue is the outer skin of a plant. 08/02/18 sclereid cells stone cells xylem conducts water moving by evapotranspiration b/c the xylem is made of dead cells.
