How are ferns and mosses different from conifers?
Mosses, ferns, and their relatives are plants that do not produce flowers but reproduce by means of SPORES. CONIFERS are non-flowering plants that reproduce by making seeds.
What makes Moss different from other plants?
Unlike most other plants, mosses don’t have roots. Instead they have rhizoids, which are small hairlike structures. Their main function is anchoring the plant to rock, bark or soil.
How are mosses and ferns alike and how are they different?
They’re Both Nonflowering Plants To reproduce sexually, mosses and ferns produce sperm and eggs. Ferns produce spores on the undersides of their fronds in cases called sporangia, and mosses produce their spores in capsules that are borne on the ends of stalks.
What are two ways that reproduction differs between mosses and conifers?
What is one characteristic of conifer reproduction that makes conifers different from mosses and ferns? Conifers produce seeds, mosses and ferns are seedless plants. [Also acceptable: Conifers do not rely on water to unite the sperm and the egg.
What type of plants are ferns and mosses?
Mosses and ferns are two types of primitive plants. Both plants are non-flowering plants. Therefore, both of them are seedless plants as well. Both mosses and ferns undergo alterations of generations.
Do conifers have true roots stems and leaves?
Conifers. A conifer has roots, a woody stem and needle-like leaves. Most conifers lose and replace their leaves all year round, so they are called evergreen. Almost all conifers reproduce by making seeds that develop in cones.
Do angiosperms have true roots stems and leaves?
Both Angiosperms and Gymnosperms are vascular plants. They have stems, roots, and leaves.
Which is the best example of anomalous secondary growth?
Bougainvillea is a member of the Nyctaginaceae and is an example of a dicotyledonous stem which displays anomalous secondary growth. In this TS, near the centre of the stem, you will see some primary vascular bundles embedded in lignified pith parenchyma.
Why does secondary growth not occur in monocots?
Secondary growth is the growth in thickness due to the formation of secondary tissues by lateral meristems. These tissues are formed by meristems, vascular cambium and cork cambium respectively. Secondary growth does not occur in monocots because monocots do not possess vascular cambium in between the vascular bundles.
Does Monocot show secondary growth?
In general, monocots do not undergo secondary growth. If they do increase in girth (like palm trees and yucca plants), it does not result in the development of a secondary xylem and phloem, since monocots don’t have vascular cambium. An increase in girth without secondary growth is referred to as anomalous thickening.
What is the importance of secondary growth in plants?
In particular, secondary growth is substantial for constant plant growth and the remodeling of body structures. As an important meristem involved, the vascular cambium forms a cylindrical domain below the organ surface producing tissues for long-distance transport and mechanical support: wood (xylem) and bast (phloem).
In which of the following plants secondary growth will not occur?
Roots and stems of monocot plants do not show secondary growth (due to absence of vascular cambium), with few exceptions e.g., Dracaena, Yucca, etc., which exhibit anomalous secondary growth.
What is primary and secondary growth in plants?
In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems and roots, causing them to elongate, and gives rise to primary tissue.
How primary and secondary growth occur in plants?
Growth in plants occurs as the stems and roots lengthen. The increase in length of the shoot and the root is referred to as primary growth. It is the result of cell division in the shoot apical meristem. Secondary growth is characterized by an increase in thickness or girth of the plant.
Can primary and secondary growth occur at the same time?
Yes primary and secondary growth occurs in same plant but not simultaneously. Primary growth occurs when the plants are young means the growth of roots and stems in length with the help of apical Meristem is primary growth.
Which are the primary and secondary roots?
There are two basic types of root systems in plants: taproot systems and fibrous root systems. Both are illustrated in Figure below. Taproot systems feature a single, thick primary root, called the taproot, with smaller secondary roots growing out from the sides.
What is the difference between primary and secondary meristem?
Hint: The major difference between primary and secondary meristem is their origin. Primary meristems are derived from promeristem, and are responsible for primary growth. On the other hand, secondary meristems originate from primary tissues and are involved in secondary growth.
