    • Both types of cells develop thick, dead cell walls and contain pits for water transport.

    • Phloem transports dissolved sugars and other organic molecules throughout the plant.

    • Phloem contains sieve-tube elements and companion cells for transport and support.

    • Leaves are the primary photosynthetic structures of most plants.

    • Photosynthesis occurs in mesophyll cells, utilizing sunlight, water, and carbon dioxide to produce sugar.

    • Plants absorb water from the soil through roots and transport it to the leaves via the xylem.

    • The epidermis of a leaf regulates the movement of gases and water vapor through stomata.

    • The xylem and phloem in leaves are arranged in vascular bundles.

    • Plant cells are larger and more easily seen due to their cell walls.

    • Animal cells have a centrosome (centriole), which is absent in plant cells.

    • Plant cells possess a cell wall, large permanent vacuoles, and chloroplasts.

    • Plant cells are typically surrounded by a cell wall, making them more easily visible with a light microscope.

    • Flowers are the reproductive organs of plants, producing seeds enclosed in fruits

    • Monocots and dicots are the two main groups of flowering plants

    • Monocots have one cotyledon, while dicots have two

    • Monocots include grasses, lilies, daffodils, tulips, palm trees, wheat, rice, corn, oats, and bamboo

    • Dicots include most broad-leafed plants, such as deciduous trees, bushes, vegetables, cacti, and many flowers

    • Monocots have thin, long leaves and bushy fibrous roots, while dicots have broad leaves and thick taproots

    • Parenchyma tissue is comprised of living cells with thin walls that perform a variety of functions, including photosynthesis, food storage, and secretion of hormones

    • Collenchyma tissue is composed of living cells with thickened, flexible cell walls that store nutrients and provide support to young and non-woody plants

    • Sclerenchyma tissue is made up of dead cells with thickened cell walls that support and strengthen the plant body

    • Most of a young plant's body is made up of cells from the ground tissue system

    • The dermal tissue system covers and protects the entire plant body

    • The vascular tissue system conducts water and dissolved substances throughout the plant body

    • Xylem transports water and dissolved minerals from the roots to the rest of the plant

    • Cell walls of collenchyma and sclerenchyma provide support and stiffness to the plant

    • Parenchyma cells make up a large portion of the storage structures in plants, such as potatoes, seeds, fruits, and roots.

    • Xylem and phloem are the two main types of conducting tissues in plants.

    • Xylem transports water and dissolved minerals from the roots to the rest of the plant.

    • Tracheids and vessel elements are the two types of conducting cells in xylem.
