Total number of known pteridophytes in the Philippines based from the 2017 Philippine Forestry Statistics

What is the arrangement of the mesophyll in the sample given?

Structure at the centermost of a dicot stem

Leaflike appendage at the base of the petiole

Commonly called the ‘mossy forest ‘ due to the abundance of mosses and liverworts that cover the branches and trunks

The structure being pointed by the arrow is called:

In roots, the procambium gives rise to:

The stomata being presented is typical of:

Looking at the cross-section of a young root, a large portion is occupied by:

What leaf modification is present in this species?

Modified leaf that protects the leaves of a newly-germinated seed

The structure presented here plays a crucial role in the initial stage of absorption in a newly-germinated seed

Which of the following cannot perform meristematic function?

What do you call a unique double organisms that consist of two unrelated components, an alga and/or cyanobacterium (photobiont) and a fungus (mycobiont).

Identify the leaf modification of the species presented?

Tissues outside the vascular cambium including the phloem constitute the

The region that gives rise new root cap cells:

Identify the structure being pointed

The sapwood include the following EXCEPT

What modified root is presented here:

As a woody stem matures, the stomata in the photosynthetic stem is replaced by:

Cut of a log made at right angle or perpendicular to the vascular wood rays:

Which among the following does NOT describe what a meristematic tissue is?

Epidermal appendage that protect plants from herbivory.

A type of growth form mostly associated among members of the fig family (Moraceae) and often start its growth as an epiphyte

All of the following are consider accessory photosynthetic pigments except for:

What is the leaf shape of this plant:

Root modification usually associated with mangrove species as it serves as a breathing organ especially during high tides

What do you call this ergastic substance produce in the vacuole can are either made of calcium oxalate or calcium carbonate?

This type of forest formation is also called Molave Forest since it is the most dominant species that can thrive in the area.

Xylary tissue with perforated plate that facilitate a more efficient movement of water and dissolve nutrient

Specific wavelength (photons) of ultraviolet light that activate most of the biological molecules.

Symplastic pathway uses the ____ for the movement and absorption of water and dissolve nutrients.

Group of plants that complete the Calvin cycle at night.

Growth hormone mostly associated with the process of abscission or natural removal of leaves from the tree

Forest formation that occurs in areas where water table is higher than the surrounding areas, with peat often about

50 cm deep or more

This stem modification is very similar to spines in structure and function but it is deeply seated and connected to the vascular tissue.

Monocot roots has a well-defined pith. The centermost portion of a dicot stem is a ground tissue called pith

Cells in the region of apical meristem or cell division are usually compacted and small due to the efficient cell division. Aside from the shoot apical bud, primary growth in the aerial parts may also be due to the presence of auxillary bud

Palms may be single stemmed or multi-stemmed (cluster­ing) because of branching from axillary buds low on the stem.In dicot and coniferous tree stems, the phloem vessel cells die and lose their contents before becoming functional as water-conducting tissue.

Xylem rays conduct water and nutrients from the inner part of the stem towards the outer stem tissues. Phloem rays are located outside the vascular cambium and usually becomes dilated hence forming a V-shaped structure

In young monocot roots, the vascular tissue is comprised of 3, 4, or 5 ridges or "arms" reaching the pericycle. Lianas is a twinning or climbing plant with relatively long stems that can be woody or herbaceous.

Once secondary growth initiates, new xylem cells are usually forms towards the exterior of the stem while toward the interior are new phloem cells. Some herbaceous plants do have vascular cambium but is only active for a short period of time and the secondary tissues produced are not very prominent

Both monocot and dicots has three tissue systems – dermal, vascular, and ground tissue systems. Pericycle is part of the vascular cylinder that gives rise to both vascular and cork cambium.

In Tropical Moist Deciduous Forest, trees are usually non-buttressed, low branching, and form an uneven branches. Primary thickening meristem (PTM) is only found among dicot stems.

Palms have no lateral meristems or vascular cambium, which in dicot and coniferous trees produce additional xylem internally and phloem and bark externally. Anahaw is an example of a pinnate-leaved palm.

The thickness of bamboo culm is largely due to the presence of lignin and silica. Most carnivorous plants thrive in areas of limited supply of protein.
