Question

The special leaves which bear seeds in conifers and cycads are called as.
(a) Chlorophyll
(b) Sporophyll
(c) Dicot
(d) Monocot

Answer 1

Hint: The embryonic leaf in seed-bearing plants, one or more of which are the first to appear from a germinating seed, is defined as "the embryonic leaf in seed-bearing plants, one or more of which are the first to appear from a germinating seed."

Complete answer: One of the characteristics used by botanists to classify flowering plants is the number of cotyledons present (angiosperms). Monocotyledonous species have only one cotyledon ("monocots"). Dicotyledonous plants are those that have two embryonic leaves ("dicots").
Option A: Chlorophyll: Photosynthesis is the process by which light energy is converted to chemical energy through the synthesis of organic compounds. Chlorophyll is a member of the most important class of pigments involved in photosynthesis. Almost all photosynthetic organisms, including green plants, cyanobacteria, and algae, contain chlorophyll.
Option B: Sporophyll: A sporangia-bearing leaf is known as a sporophyll. Sporophylls can be microphylls or megaphylls. Sporophylls (whether microphylls or megaphylls) in heterosporous plants bear either megasporangia or microsporangia and are thus referred to as megasporophylls or microsporophylls.
The dicotyledons, or dicots, were one of two groups into which all flowering plants, or angiosperms, were previously divided. Chlorophyll is a molecule that absorbs sunlight and converts it into carbohydrates by combining \[C{{O}_{2}}\] and water. Monocotyledons, or monocots, are flowering plants whose seeds typically contain only one embryonic leaf or monocot.
Option C: Dicot: The dicotyledons, also known as dicots (or, less commonly, dicotyls), are one of two groups into which all flowering plants, or angiosperms, were previously divided. The name refers to one of the group's distinguishing characteristics, namely the presence of two embryonic leaves, or cotyledons, on the seed.
Option D: Monocot: Monocotyledons, also known as monocots, are grass and grass-like flowering plants (angiosperms) with only one embryonic leaf, or cotyledon, in their seeds (Lilianae sensu Chase & Reveal). They are one of the major groups into which flowering plants have traditionally been classified, the rest of which have two cotyledons and are thus classified as dicotyledons, or dicots.

Thus, the answer is option B: Sporophyll.

Note: Sporophylls are not produced by all plants. Sporangia is a type of sporangium that grows on stems. On the terminus of a stem, Psilotum is thought to produce sporangia (fused into a synangium). Equisetum always produces strobili, but sporangiophores (sporangia-bearing structures) have been interpreted as modified stems. Despite their curvature, the sporangia are interpreted as terminal.
