Roots and Stems
![Page 2: PLANTS- Structure Roots and Stems. ROOTS-Function 1. Anchor the plant to the soil 2. Absorb water and minerals from the soil 3. May store food 4. Transport.](https://reader036.fdocuments.in/reader036/viewer/2022082818/56649ef35503460f94c057c8/html5/thumbnails/2.jpg)
ROOTS-Function 1. Anchor the plant to the soil 2. Absorb water and minerals from
the soil 3. May store food 4. Transport water and dissolved
substances from the root into the stem

ROOTS-Types
1. Tap-store large amounts of food and water Example-Carrot
2. Fibrous roots-absorb water and anchor the plant Example-grass
3. Combinations of those two as well as other specialized root systems

ROOTS-Growth -Meristems: areas of rapidly dividing
cells -Apical meristem: causes root to grow
longer, located at the tip of the root behind the root cap (the protective covering)
Vascular cambium: adds cells to increase roots diameter located between the xylem and phloem

STEMS-Function 1. Support the aboveground parts of
the plant 2. Expose the leaves to sunlight 3. Sometimes photosynthesis (if
they are green) and food storage occur in the stem
4. Transport materials

4. Transport-
Xylem tissues transport water from the roots to the leaves
Phloem tissue transport sugars, minerals, and hormones throughout the plant (food)
Translocation is the term used to describe movement of sugars from the leaves through the phloem

STEMS-Types 1. Herbaceous stems-soft, green,
flexible; usually carry out photosynthesis; Examples are daisies, carnations, petunias
2. Woody stems-hard and rigid; add thickness, called secondary growth (wood)

STEMS-Growth Apical meristem produces new cells,
located at the top of the stem, growth in length
Lateral meristem or vascular cambium increases stem’s diameter
