Dicot Leaf Epidermis

Lower leaf epidermis of the stonecrop plants showing puzzle shaped epidermal cells with scattered stomata. Stomata (singular: stoma) are like little mouths on the leaf surface, specialized in gas-exchange – CO2 enters a plant through them. The pairs of sausage-shaped cells, like the lips of these mouths, are “guard cells”, which guard the opening and closure of the stomata. In many flowering plants, the stomata … Continue reading Dicot Leaf Epidermis

The Birth of a Flower

Unlike animals, plants possess the ability to generate new tissues and organs throughout their entire lifespans due to the activity of stem cells located in specific sites termed meristems. During the reproductive phase, floral meristem (lower right dome-shaped structure) give rise to different floral organ primordia (the series of bulges), which will eventually grow into the sepals, petals, stamens, staminodia, and carpels of a beautiful … Continue reading The Birth of a Flower

As the rocket speeds up and shoots through the atmosphere, flames trail behind it. Eventually, a part of the rocket falls off, falling back towards the earth. This part of the rocket is called the booster. The booster … Continue reading Recycled Rockets? Company Pioneers the First Reusable Rocket

Diamonds in the Leaf

This cross section of an oleander (Nerium oleander) leaf reveals two beautiful mineral crystals inside. Leaf cells are stained red. Adapted to dry conditions, this leaf possess three epidermal layers to prevent water loss, below which there are tightly packed palisade mesophyll cells that are specialized for harvesting light and loosely packed spongy mesophyll cells allowing efficient gas exchange. These calcium oxalate crystals are deposited by specialized … Continue reading Diamonds in the Leaf
