Plants

Plants are multicellular organisms in the kingdom Plantae that use photosynthesis to convert sunlight into chemical energy. They have been important sources of food, shelter, and medicine for humans since ancient times. Plants vary greatly in size and shape; some are microscopic while others can reach up to 100 feet tall or more.

Most plants contain chloroplasts which produce oxygen as a byproduct of photosynthesis. In addition, many plants produce flowers which attract pollinators such as bees, butterflies, moths and other insects. This helps ensure genetic diversity among plant species over generations through cross-pollination.

Plant cells differ from animal cells in several ways including having cell walls made up of cellulose rather than protein like animals do; this gives them their rigid structure allowing them to stand upright against gravity without muscle support like animals require for movement (or locomotion). Additionally they lack organelles found within animal cells such as lysosomes or mitochondria meaning most plant processes must occur on the plasma membrane itself rather than inside specialized cellular compartments like those seen with animals..
The life cycle of a typical flowering plant starts with germination where water is absorbed into its seed coat bringing it out of dormancy before growing root structures which anchor it into the soil providing access to nutrients necessary for growth along with moisture control over its environment – these roots may take various shapes depending upon the type & age/stage of development being observed (e.g., taproot vs fibrous root systems) . Above ground portions consist primarily leaves arranged around stems holding each leaf aboveground so light can be captured efficiently but also act as an additional means gathering nutrients from rainwater runoff when available . Photosynthetic activity occurs mainly within green parts such leaf blades although certain varieties may possess modified organs specifically adapted towards performing light capture & chemical processing operations instead known collectively under group name “chlorophyll” – these help store energy until further needed during reproduction process later down line ..

Finally fruits develop after successful flower pollination containing seeds ready disperse away new location thus continuing lifecycle anew , additionally secondary products often developed alongside primary fruit components aiding dispersal efforts either way whether via ingestion passing mammals birds alike who feed off juicy fleshy parts consuming any contained therein then excreting elsewhere intact unharmed
