Chapter 1-Exploring Botany OO Flashcards
The study of plants, including plant structure, function, reproduction, diversity, inheritance
Botany
Plants remove… from the atmosphere, helping to keep your planet from getting too warm for life as you know it
Carbon Dioxide
Cells that have a nucleus and cellular organelles.
eukaryotic cells
Most leaves are flat because that is the best shape for …
spreading out and catching lots of sun
Plant stems support the leaves, holding them in different arrangements so that they dont shade each other and…
can absorb the most light
Plant roots are in charge of getting water for the leaves and stems by
absorbing water from the soil.
Extra roots that start from the stem above ground and then grow down to sink into the earth.
prop roots
Plants reproduce sexually, they make special reproductive cells called
Spores
These protect the plant embryos they carry and nourish them with stored food
Seeds
Some plants that do sexual reproduction get fancy and produce showy flowers designed to ƒ
attract animals to help spread their pollen around.
Flowers contain… that will participate in sexual reproduction.
the male and female parts of the plant
…comes from the male part of flowers, carrying and protecting the plant sperm. .
Pollen
The female parts of flowers house the
ovules that contain the eggs
This occurs when pollen arrives at the female part of the flower.
Pollination
When pollen releases the sperm so that they can fuse with the egg, causing
Fertilzation
Plants need a source of building material, called
Matter
Plants make their own food through the process of
Photosynthesis
a series of chemical reactions that basically unpack food molecules, making the matter and energy available to cells.
Cellular Respiration
Plants transport dissolved sugars using a special type of tissue called
phloem
they transport water and dissolved minerals using a tissue called
xylem
This aides in direct their growth and development
Hormones
Plants grow when groups of cells at their tips, called…divide in two to produce new cells
apical meristems
The process of cell division that adds new growth is called
mitosis
The sperm and egg, which are produced by a type of cell division called
meiosis
