In many vascular plants, secondary growth is the result of the ___
The vascular cambium is a ___ that divides to produce ___ cells on the inside of the meristem and ___ cells on the outside.
meristem, secondary xylem cells, secondary phloem cells
Secondary increases the ___ of the root and stem.
Do plants with secondary growth usually develop a cork cambium?
The ____ gives rise to thickened cork cells to protect the surface of the plant and reduce water loss.
Lost some nonwoody plants that secondary growth also occurs in.
- 1. tomato
- 2. potato tuber
- 3. carrot taproot
- 4. sweet potato tuberous root
The first root to come from a plant is called the ___
The vascular cambium lies between the ___ and the ___.
Secondary xylem cells form on the ___ cambium cylinder.
Cells forming on the outside of the cambium cylinder are called ___
secondary phloem cells
The ___ forms the periderm.
The periderm consists of protective ___ cells that cotain suberin.
In roots, the cork cambium originates in the ___, a component of the vascular cylinder.
Stems usually consist of three tissues, what are they?
- 1. dermal tissue
- 2. ground tissue
- 3. vascular tissue
The ground tissue of stems consists mainly of ___ cells and fills in around the vascular tissue.
___ stem with promary growth have pith in the center.
In dicot stems, what is the function of the stomata?
Gas exchange and multicellular stem hairs
What is xylem?
Xylem is one of two types of transport tissue in vascular plants.
Secondary xylem is formed ___
during secondary growth from vascular cambium
What are the 2 main groups that secondary xylem can be found in?
- 1. Conifers
- 2. Angiosperms
What does xylem do?
Xylem transports water and soluble mineral nutrients from the roots throughout the plant.
What is phloem, and what does it do?
Phloem is one of two types of transport tissues found in vascular plants. Phloem carries organic nutrients (glucose in particular) to all parts of the plant where needed.
In trees, the phloem is the ____ layer of the bark.
The ___ is concerned mainly with the transport of soluble organic marerial made during photosynthesis. It is called translocation.
Phloem tissue consists of 3 types of cell. What are they.
- 1. Parenchyma
- 2. Sieve-Tube
- 3. Companion
What is pith?
Pith is a tissue found in the stems of vascular plants. Composed of soft. spongy, parenchyma cells. The pith is circled by a ring of xylem, with a ring of phloem outside of that.
What is vascular cambium?
Vascular cambium is a part of the morphology of plants. It consists of cells that are partly specialized, for the tissues that transport water solutions, but have not reached any of the final form that occur in their branch of the specialization graph.
