Make up the bulk of the plant body- includes 3 types of simple tissue:
Parenchyma cells: have thin walls and are active in photosynthesis and storage
Collenchyma cells: provide support for primary tissues
Sclerenchyma cells: Fibrous cells that give stalks their gravity-resisting strength
, Nucleus in the center that contains protons (positively charged) and neutrons
(no charge). The outermost region is called an electron shell that contain the
electrons (negatively charged)
Present in the walls of the stomach, bladder, lungs, and other organs
- Responsible for gut motility, bladder emptying and other organ functions
Support and anchor the aboveground portion of the plant, and carry water and
food from place to place within the plant

Cellular respiration is the process that releases energy from food in the presence
of oxygen.
Attached to bones- functions in moving the body and its part
- under voluntary control by the nervous system
Plants that are well adapted for growth in moist habitats
- Have no vascular tissues, instead they have threadlike structures for
absorbing water and solutes
, Caries the required amino acids from the cytoplasm to the ribosome for protein
synthesis. Helps to arrange the amino acids into the proper sequence for the
synthesis of proteins
