Question: How is pinnately compound leaf different from palmately compound leaf?

Answer:

Pinnately Compound Leaf:

Leaflets: Pinnately compound leaves have leaflets arranged along a central axis called the rachis. The leaflets are attached in a feather-like or pinnate pattern.
Arrangement: The leaflets of pinnately compound leaves are arranged on opposite sides of the rachis, forming pairs or sometimes in an odd number of leaflets.
Example: Examples of plants with pinnately compound leaves include neem (Azadirachta indica) and rose (Rosa spp.).

Palmately Compound Leaf:

Leaflets: Palmately compound leaves have leaflets attached to a common point at the tip of the petiole, resembling the fingers of a hand or a palm.
Arrangement: The leaflets of palmately compound leaves radiate out from a central point, and their arrangement is similar to the spokes of a wheel.
Example: Examples of plants with palmately compound leaves include horse chestnut (Aesculus hippocastanum) and umbrella plant (Schefflera spp.).

is the conversion of sunlight, carbon dioxide (CO2), and water into food (sugars) and oxygen by plants, algae, and some microorganisms. Light energy is collected and used by green plants during the process to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic molecules.

The “ ” is a phenomenon which occurs twice in a year; it takes place when the sun is at a 90- degree angle to the Earth’s surface or when the sun is just overhead. This moment makes the person’s or any object's shadow completely disappear for few minutes.

Zero shadow day, is a day on which the sun does not cast a shadow of an object at noon.

Zero shadow can be observed for about a minute twice a year in the city.

The sun is not positioned exactly above us everyday as zero shadow day happens only in countries situated between the tropic of Capricorn and the tropic of Cancer.

It is considered that Eratosthenes, a Greek mathematician had calculated the circumference of the earth on zero shadow day,”

In Heterotrophic nutrition, the biologic oxidation of organic compounds, such as glucose occurs , to yield ATP and simpler organic (or inorganic) compounds, which are needed by the bacterial cell for biosynthetic or assimilatory reactions.


Respiration is a type of heterotrophic metabolism that uses oxygen and in which 38 moles of ATP are derived from the oxidation of 1 mole of glucose, yielding 38 ATP energy energy.


In fermentation, another type of heterotrophic metabolism, its the way to get energy from fuels anaerobically (in the absence of oxygen).Less energy is generated from this incomplete form of glucose oxidation.

is an ancient metabolic pathway, meaning that it evolved long ago, and it is found in the great majority of the time organisms alive today.

Ancient prokaryotes used glycolysis to make ATP way before oxygen even existed. Due to no requirement of oxygen, the first prokaryotes generated ATP only through glycolysis, due to the fact that it can be performed without oxygen.

To , Glycolysis is the first set of reactions for extracting energy from sugar molecules. Universal to almost all organisms, eukaryotes and Prokaryotes. It Doesn't require oxygen. Occurs in the cytosol of all cells and involves soluble enzyme.
