Definitions
Endosperm- this tissue is produced
inside the seeds of most flowering plants. It surrounds the embryo and provides
nutrition like starch, oil and protein. It helps the newly fertilized plant get
the nutrition it needs’

Ethylene-gaseous organic compound with the formula C2H4 and is an unsaturated hydrocarbon because
of its double bond. It helps the plant to stimulate flower opening, stimulate
fruit ripening, and stimulate fruit growth.

Gibberellins- plant hormones that regulate growth and influence processes like stem
elongation, and dormancy. There are 123 different types of gibberellins
identified in various plants, fungi, and bacteria

Bryophyte-refers to all land plants that do not have vascular tissues. Vascular tissues include
the xylem and phloem. They don’t produce flowers or seeds. Some examples of
bryophytes are liverworts and mosses.

Lignin-fills in spaces between cellulose and other parts of the cell wall like xylem. It
helps to build strength of the cell wall. Because it is hydrophobic, it helps
the water get to the places it needs to be absorbed at quicker. It makes it
possible for the plant to conduct water efficiently.

Long day plant- a plant that flowers only when the light period is longer than a
critical length. They usually flower in late spring or early summer. An example
of this plant is spinach. It needs a lot more light than
darkness.

Meristems- embryonic tissues that make a plant capable of indeterminate growth. One type of
meristem is an apical meristim, located at the tips of roots and in the buds of
shoots, providing additional cells that enable the plant to grow in length.
Meristems are important to plants because these tissues make them grow for a
lifetime.

Phloem- tissue that carries nutrients like glucose to places where the plants need it.
Without this tissue, plants would die because they would not be able to receive
the proper nutrients.

Abscisic acid-slows growth of a plant. In seed dormancy, it prevents seeds from
germinating in the dark, and makes sure they germinate in the spring. In
addition, as soon as a plant begins to wilt, this acid accumulates in the leaves
and cause the stomata to close rapidly. Abscisic acid is important because it
tells plants the appropriate time to germinate and it helps the plant protect
itself when it wilts.

Xylem- this tissue carries water and minerals from the roots up into the plant. It also
helps replace the water lost during transpiration and photosynthesis. The water
comes up through capillary action. Without the xylem tissue, water would have a
hard time traveling around the plant and water would most likely not be replaced
during transpiration and photosynthesis.

Angiosperm- An angiosperm is any
flowering plant. It can be found any where in your backyard or any biome like
the Tropical Rainforest. 100_4854.JPG


autotroph-organism that makes complex organic compounds by the means of photosynthesis. It is any plant. They
support the rest of the trophic levels on earth.

Conifer leaf- These leaves are
like the prickley green things you will fine on a pine tree.

Cuticle layer of a plant- This layer can be found on an inner layer in a leaf It feels very waxy to the touch and It helps the plant protect itself against UV radiation.

deciduous leaf- these leaves can be found on plants that shed their leaves once a year, like in the fall.

fruit-fleshy with seed-this is the typical fruit you eat everyday in your home.You can always seeds in them. for ex.. apples, and watermelon.

Ovary-in flowerinng plants the ovary is found insdie the petals. 100_4859.JPG





Frond- a divided leaves that are found on ferns.

Genitically modified organism- an organism who has been genetically modified by scientists. For example corn has been genetically modified to have more carotene and to have more vitamin C. Tomatoes are meant to be larger.

Pollinator- an object like a bee
that moves the pollen to the female’s stigma. This can also be accomplished by
hummingbirds and mammals like monkeys.

Thorns of a plant- Thorns can be

found on the stems of plants like rosees. Thye protect the plant from getting

eaten. Herbivores won’t want to eat plants because thetorns will be sharp in

their mouths.

pteridophyte-vascular plants that

don’t produce flowers nor seeds. they reproduce via spores.
