Kindle Notes & Highlights
eukaryotic cells,
New plant growth occurs at stem tips as cells divide to make stems grow longer
Flowers contain the male and female parts of the plant that will participate in sexual reproduction. Pollen comes from the male part of flowers, carrying and protecting the plant sperm. The female parts of flowers house the ovules that contain the eggs.
Ionic bonds can be very strong in dry environments like salt crystals, but they’re weak in the watery world of plant cells.
Covalent bonds are the strongest bonds in plant cells, creating the backbones of the molecules that form the cell.
Almost all eukaryotic cells, including those of plants and animals, contain the following structures: Plasma membrane Ribosomes Cytoplasm Nucleus Endoplasmic reticulum Golgi apparatus (sometimes called dictyosomes in plant
Mitochondria Cytoskeleton Vesicles, vacuoles, and lysosomes In addition, plants have four structures, some of which are found in other eukaryotes, but which are not found in animal cells): Cell wall Plastids, including chloroplasts Large central vacuole Plasmodesmata
