You can find an example of collenchyma cells in stalks of celery-those wispy strands running the length of the celery are collenchyma cells. CollenchymaĪ cell type that functions in supporting the plant. Cohesion makes water molecules stick together, so a column of water moves as one entity instead of many molecules moving separately. The water is under tension, because it is evaporating out of the leaves.

The explanation for water movement in the xylem. Bud scales protect buds before they open up and grow into shoots. Modified leaves that form a scale, covering a new bud. Consider it one of the main construction zones of the plant. Apical meristemĪ zone at the tip of a shoot or root where lots of cell division occurs, adding to new growth. Same idea with a plant, but apical can refer to both the tip of the shoots and the tip of the roots. If you climb to the top of the mountain, you’re at the apex. Yep, the ones with all the pretty petals and yummy fruits, like apples, cherries, and watermelon? Where's a fruit stand when you need one? Angiosperms are also the most common plant group on Earth. A sporophyte generation (2 n) makes a gametophyte ( n) plant that then makes a sporophyte, and this process goes on and on, generation after generation. Even though the plant only has half the genetic information, it can still make a whole plant. Each generation of plants alternates being haploid ( n) or diploid (2 n)-that is, every other generation has half the genetic information that the others have.

Plant Biology Terms Alternation of GenerationsĪ weird, funky lifestyle that all plants and some algae have.

Flower that starts with phlo
